The semiconductor integrated circuit (IC) industry has produced a wide variety of digital devices at decreasing cost to address issues in a number of different areas. This has been achieved at least in part due to increasing integration density. The integration density of various integrated circuit components such as transistors, diodes, resistors and capacitors have benefited from continual reductions in minimum feature size that in turn allow more components to be integrated into a given area. Because reducing minimum feature sizes through photolithographic improvements is becoming increasingly difficult, recent improvements in integration density have been achieved with new three dimensional integrated circuit (3DIC) structures having multiple layers. However, while higher integration density has allowed various radio frequency (RF) circuits and analog to digital converter (ADC) circuits to improve integration density, the corresponding demands on capacitors used by those RF and ADC circuits have also increased. It would be beneficial to mitigate or resolve problems associated with capacitors in 3D ICs.
